Description:
A vulnerability has been reported in Microsoft Windows, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the "CanonicalizePathName()" function in netapi32.dll and can be exploited to cause a stack-based buffer overflow via e.g. a malicious NetrpPathCanonicalize RPC request with an overly long path name to the Server Service (port 139/TCP or 445/TCP).

Successful exploitation allows execution of arbitrary code.

NOTE: According to Microsoft, the vulnerability is already being actively exploited.

Another unspecified issue discovered by Microsoft has also been reported.
